Description

Technical Field

[0001] The utility model belongs to the technical field of fireworks production, in particular to a fuse fixing device for fireworks production. Background Art

[0002] In the process of fireworks production, fuse is an indispensable raw material. However, with the advancement of production technology, in mechanized large-scale production, bundles of fuse need to be pulled to processing equipment for use. After the fireworks fuse is produced, it is often necessary to fix the fuse and then use shearing equipment to cut the fireworks fuse.

[0003] The existing protection device only uses a single pair of scissors to cut the burning fuse when in use. However, since the fuse burns quickly, when the scissors are picked up to cut it, it will be found that the burning point has exceeded the position of the scissors. The cutting position cannot be determined, and the fuse cannot be quickly cut off according to the position of the burning point. This not only easily causes chaos on the scene, but also makes it difficult to cut off the burning point, and even causes other leads on the winding device to ignite, reducing safety and endangering the life of the operator.

[0004] The utility model aims to provide a fuse fixing device for fireworks production to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fuse fixing device for fireworks production, comprising a supporting base plate and two supporting upright plates symmetrically welded on the top surface of the supporting base plate, a lead winding wheel for winding up the fireworks fuse is rotatably installed between the two supporting upright plates, a servo motor is installed on the outer wall of one of the supporting upright plates, the output shaft of the servo motor is connected to the lead winding wheel, one side of the supporting base plate is detachably connected to an extension plate, a lead tube for the fireworks fuse to pass through is arranged on the top surface of the extension plate, a hydraulic column is slidably installed on the bottom of one end of the lead tube close to the lead winding wheel, the hydraulic column is longitudinally installed on the extension plate, the other end of the lead tube is hinged to the upper part of the extension plate, two cutting edges are symmetrically penetrated on the top surface of the lead tube, and a first lifting cutting knife and a second lifting cutting knife for cutting the fuse according to the position of the fuse burning point are respectively installed on the top of the lead tube, one in front and one in the back.

[0006] Preferably, a hinged vertical plate is symmetrically welded to the top surface of one end of the extension plate away from the supporting bottom plate, and one end of the lead through-tube away from the lead winding wheel is hinged to the hinged vertical plate through a pin.

[0008] Preferably, electric lifting rods are fixedly mounted on the top surfaces of the first lifting cutting knife and the second lifting cutting knife, and the tops of the electric lifting rods are connected to the inner top wall of the U-shaped bracket plate.

[0009] Preferably, the top lifting end of the hydraulic column is hinged with an inverted U-shaped slider via a pin, and the bottom surface of the wire threading tube is provided with a sliding groove for the U-shaped slider to be slidably connected.

[0010] Preferably, an extension inner plate is welded to one end of the extension plate close to the supporting bottom plate, and a plug hole for plugging the extension inner plate is formed on a side of the supporting bottom plate facing the extension plate.

[0013] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0014] The fuse fixing device for fireworks production uses a hydraulic column to drive the lifting height adjustment of the fuse threading tube. During the lifting process, the other end of the fuse threading tube is hinged and rotated between two hinged vertical plates under the action of the pin shaft, so that the angle and position of the fuse threading can be adjusted to meet the use of different angles and positions;

[0015] When the lead wire is passed through the lead wire tube and ignites, in order to cut off the ignition point and prevent the lead wire on the lead wire winding wheel from igniting, the first lifting cutting knife or the second lifting cutting knife is controlled to descend by the electric lifting rod according to the position of the ignited lead wire, so that the first lifting cutting knife or the second lifting cutting knife just descends to the cutting edge to cut the lead wire in the lead wire tube. If the ignition position is close to the first lifting cutting knife, the first lifting cutting knife is used for cutting; if the ignition point is close to the position of the second lifting cutting knife, the second lifting cutting knife is used for cutting, thereby preventing the lead wire on the lead wire winding wheel from igniting, thereby improving safety.

[0028] An extension plate 5 is detachably connected to one side of the support base plate 1. A wire threading tube 7 is provided on the top surface of the extension plate 5 for the firework fuse to pass through. A hydraulic column 10 is slidably installed at the bottom of one end of the wire threading tube 7 close to the wire winding wheel 3. The hydraulic column 10 is longitudinally installed on the extension plate 5. The other end of the wire threading tube 7 is hinged to the upper part of the extension plate 5.

[0029] The hydraulic column 10 drives the wire threading tube 7 to adjust the lifting height. During the lifting process, the other end of the wire threading tube is hinged and rotated between the two hinged vertical plates 6 under the action of the pin shaft, so that the angle and position of the wire threading can be adjusted to meet the use of different angles and positions.

[0038] The lead fixing device for fireworks production is characterized in that a support bottom plate 1 is installed on one side of the lead production equipment by bolts, and a servo motor 4 runs on one of the support vertical plates 2, thereby driving the lead winding wheel 3 to rotate between the two support vertical plates 2, so that the lead winding wheel 3 can wind up the lead, and the lead is passed through the lead threading tube 7 for use. When the lead is passed through the lead threading tube 7 for use and the lead is ignited, in order to cut off the ignition point and prevent the lead on the lead winding wheel 3 from being ignited, according to the position of the ignited lead, the first lifting cutting knife 8 or the second lifting cutting knife 9 is controlled to descend by the electric lifting rod 16, so that the first lifting cutting knife 8 or the second lifting cutting knife 9 is just dropped to the cutting edge 15, and the lead in the lead threading tube 7 is cut. If the ignition position is close to the first lifting cutting knife 8, the first lifting cutting knife 8 is used for cutting, and if the ignition point is close to the position of the second lifting cutting knife 9, the second lifting cutting knife 9 is used for cutting, so as to prevent the lead on the lead winding wheel 3 from being ignited;

[0039] The hydraulic column 10 drives the wire threading tube 7 to adjust the lifting height. During the lifting process, the other end of the wire threading tube is hinged and rotated between the two hinged vertical plates 6 under the action of the pin shaft, so that the angle and position of the wire threading can be adjusted to meet the use of different angles and positions. The extended inner plate 13 and the socket 11 are installed in coordination. The socket 11 connected by the extended inner plate 13 can adjust the position of the extension plate 5 to meet the distance required in actual use.
